Thanks.  The first obstacle here is that lib/Makefile is being generated
like such:

@GL_GENERATE_ALLOCA_H_TRUE@alloca.h: alloca.in-h
@GL_GENERATE_ALLOCA_H_TRUE@     $(AM_V_GEN)rm -f $@-t $@
@GL_GENERATE_ALLOCA_H_TRUE@     { echo '/* DO NOT EDIT! GENERATED 
AUTOMATICALLY! */'; \
@GL_GENERATE_ALLOCA_H_TRUE@       cat $(srcdir)/alloca.in-h >> $@-t
@GL_GENERATE_ALLOCA_H_TRUE@     } > $@-t
@GL_GENERATE_ALLOCA_H_TRUE@     mv -f $@-t $@
@GL_GENERATE_ALLOCA_H_FALSE@alloca.h:
@GL_GENERATE_ALLOCA_H_FALSE@    rm -f $@

The @GL_GENERATE_ALLOCA_H_* parts should have been replaced by
sedlibmk.inp, correct?

Thanks.
